What ToneMatrix actually is

Audiotool's sequencer is a sixteen-by-sixteen grid tuned to a pentatonic scale, with a playhead sweeping steadily from left to right. Lighting up a cell makes it chime and sends a ripple outwards across the surrounding squares, so the grid behaves like water.

Why it is worth your time

The ripple animation lets you see the rhythm as interference patterns a moment before you hear it.
